HEATING AND f COOLING?y sYs'rEi'rI FOR WINDOWS, DOOR-s; AND THE'fLIKE:

Application filed.v September 22, 1922. Serial No. 582,909.4-

Be it known that Ij, IRWIN H. ERB, a citizen of the United States, and aresidentof Test Liberty, in the vcounty of `Muscatine and Stateof Iowa,have invented-acertain new and useful Heating and? Cooling' System forVindows,fDoors, andthe like, of which the following is a specification.

The object of my invention is to providea heating` and cooling.systeinvfo'r windows, doors and the like, particularly designed forwarming or' coolingf theyair thatfpasscs into a building aroundV awindow ordoor and-for supplying cool-or warm" air,. as maybe delsired,^adjacent to the' joints around a window OrdQOn lVith thisandotherobjects in View, my invention consists in the construction,`ar-` rangement and combination ofthe various parts of myv device,whereby the objects coni templated are attained, as hereinafterfmerefully set forth, pointed out inmy claims,l

and illustratedin the accompanying drawings',in which:

Figure 4 is a horizontal, sectional view taken on the line 4 4 of Figure3.

In general, it may be said that my invention consists in providing inconnection with the ordinary frame around a door or Window a secondaryframe made of tubular material, arranged to afford a stop for the dooror window supported in the ordinary frame, and adapted to serve as anair conducting means. e

In the accompanying drawings, I have illustrated my invention inconnection with a window having two sashes.V

In the drawings, I have used the reference numeral 10 to indicategenerally the ordinary frame of the Window, having the stool 11 and thesill 12.

Slida-bly mounted on the main frame 10 and arranged to pass each otherin the ordinary way are upper and lower window sashes 13 and 14.

My secondary frame consists of tubular members forming stops between thetwo sashes. The secondary frame Yhase top member 1 5, side members 16communicating therewith and bottom members l. 1-7, extend; ingv towardeach other fromthe yside me-mresse bers 16 to the middleoffthefwindowatthe bottom thereof.

members-18 and 19. Oneofthe-members 18 The adjacent ends:ofthe.me-Inhersv u or 19v may be;comieetedv .withjfa suitable source-0f hot airsupply o r a suitable source f ofcold air suppl'yvand theA` other-rmemberL 18 or 19 may be connected for pro-r vidingcirculationof hotorcoldlair. The members 16; Vforrrrupright'part-ing strips betweenthesashes13 and14' and thus form apart of the windo'w"framefinstallation.- Y l The'member 15 forms a' partingstrip for the insideof theupper`saslrandfor the out@ sideof the lower sashwhen. thelatter vis raised.Similarly the `members 17 form parting, strips for the upper and lowerVThe.;members lfmay be .connected midway between"` the top andv bottomthe window bymeans-ofa cross member 20.5

V:Itwill be understoodthat the members of theV second arywframe are.connected to-v gether for affording, acireulationof air entirelyaround'the main windowframe.;

For instance, afterhot or cold airis fsup;

pliedth-rough the member 19it will pass thiush, the. rellghan-'Hlelbgel" 17 thnlc upwardly through the right-hand member 16 across tothe other member 16 through the members 20 and 15 and thence downwardlyto the other member 17 and the member 18.

The members 17 are preferably inset in the sill 12, as shown in Figure3. V

' 0n their inside faces, the members 17 are Y.

provided near their upper portions with one or more openings 22 forallowing the exit of air. u

Similarly, the inner faces of the lower edges of the members `16 areprovided with openings 23. The member 20 is provided vith one or moreopenings 24 on its inner ace. Y

The upper portions of the members 16 and the member 15 are provided intheir .outer faces adjacent to the sash y13 with one or more openings25.

The openings 22, 23, 24 and 25 are intended tobe conveniently located,so as to beladf Y around window or-door frames. One ob]ec tion to suchdevices is that it is ordinarily desirable to allow some air to passaround the windows or doors in order that fresh air may be suppliedtothe interior of the building or room.

Where my device is employed, fresh air may be supplied through thesecondary frame and any air coming in around the window sashes will bewarmed or cooled both by contact with the warm or cold secondary frameand by mixture with the warm or ,cold air escaping therefrom.

The secondary frame forms a part of the main window frame and the totalcost of installation of the secondary frame is therefore' reduced by thesaving accomplished by the omission of the ordinary parting strips,

for which the 'secondary frame is a substitute.

It will be seen that where my invention is used, the temperature of aroom may be quite accurately controlled by controlling the volume andtemperature of the air passing through the secondary frame.

Even in hot summer weather, when the window sashes are opened, thetemperature of the room can be cooled by supplying cold air fromA thesecondary frame to the draft of air passing inwardly through the window.

lBy simple and suitable modifications, which are within the skill of anintelligent workman, the installation can be modified so as to adapt itfor use around a door and around windows of di'erent kinds, sizes andshapes. Y

The lower window sash may be provided with a metal awningfor covermember 26, such as is illustrated in Figure 3, adapted to cover and fitover the/members 17 when the lower window sash is closed.

It is my intention to cover by the claims of my patent, anymodifications in structure, which may be reasonably included within thescope of those claims, and I have shown in my drawings simply anillustrative embodiment of my invention.

I claim as my invention z' y 1 l. In a deviceof the class described, thecombination of aV main frame, a pair of window sashes slidably mountedtherein, a tubular air conducting frameon themain frame arranged betweenthe'sashes to form parting strips therefor. f

2. In a device of the class described, the combination of a main frame,a pair of window sashes slidably mounted therein, a tubular airconducting frame on the main frame arranged between the sashes to formparting strips therefor provided with airY exit openings adjacent to thepath of air coming in around the sashes. 1

3. In a device of the class described, the combination of a frame, akpairjof window sashes slidably mounted therein, a secondary frame oftubular material supported on said first frame and arranged to form aparting strip structure for the sashes, and including a bottom memberand a covermember mounted on the lower' sash adapted to cover andprotect the lower member` of the secondary frame when the lower sash Yisin its lowermost position.
